Zusammenfassung

Many social traits have direct and often severe fitness consequences; yet these traits vary considerably, both, within and between individuals. The proposed project will explore two explanations: First, fixation of social traits can be constrained by the genetic architecture, e.g., when antagonistic selection acts on two pleiotropically linked traits. The project team will use long-term data from a wild, pedigreed population of house-sparrows - a classic model species - to quantify genetic correlations in a set of pleiotropically linked characteristics: social behaviour (dominance and...
